SPECIFICATION forming part of Letters Patent No. 737,406, dated August 25, 1903.

Application filed December 12, 1901. Renewed May 29, 1903- Serial No. 159,873. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES L. HILDRETH, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Ooiler- Heads for Oarding-Engines, &c., of which the following description, in connection with the accompanying drawings, is a specification, like figures on the drawings denoting like parts.

My invention is embodiedin a coiler for carding-engines and drawing-frames or for other machines employed in the working of fibrous materials, and relates, mainly, to the provisions for enabling lubricant to be supplied to the bearings which are located in the upper part of a coiler.

The invention consists in the features and combinations, which will first be described in connection with the drawings, which latter show the preferred embodiments of the various features of improvement, and then will be particularly pointed out and distinctly defined in the claims at the close of the specification. 7

In the drawings, Figure 1 shows in plan, with the door open, the top of a coiler having my present invention applied thereto. Fig. 2 is a view thereof in vertical section on the plane that is indicated by the dotted line 22 22, Fig. 4, looking in the direction indicated by the arrows adjacent the ends of the said line. Fig. 3 is a view, mainly in vertical section, along the line 15 15 of Fig. 4. Fig. etis a view in plan with the cover portion and its appurtenances removed. Fig. 5 is a side elevation of the movable stand containing the bearing for one of the coiler-rolls. Fig. 6 is an elevation thereof looking at the lefthand end of the same in Fig. 5. Fig. 7 is a plan thereof. Fig. 8 is, an end elevation of the fixed stand containing the bearing for the other of the coiler-rolls. Fig.9 is a plan thereof. Fig. 10 is a view in vertical crosssection on the plane indicated by the dotted line 13 13, Fig. 4. Figs. 11 and 12 are respectively an end elevation and a side elevation of the oil-cup which is employed in connection with the bevel-gear at the upper end of the upright shaft of the coiler. a plan of the said oil-cup.

Having reference to the drawings,'1 desig nates the side casing for inclosing the machinery of a coiler-head upon all sides thereof. 2 is the coiler top or cover for inclosing that machinery upon its top, the same being connected with the said side casing 1 by means of one or more horizontal pivots at one end, as at 3, Fig. 3.

4 is a raised sliver-guide affixed to one end of the said cover portion 2, and 5 is a trumpet applied and secured to the top of said cover portion near the other end of the latter and having the downwardly-projecting lower portion. thereof located in an opening 6 in the said cover portion.

7 and 8 are the coiler-rolls, arranged below the said trumpet, and 9 is a portion of the rotatingcoiler-plate, the inclined sliver-passage Fig 13 is through the latter being designated 91.

As will be understood by those skilled in the art, the sliver under treatment passes in the usual manner over the raised sliver-guide 4, through the passage of the trumpet 5, between the coiler-rolls 7 and 8, and through the sliver-passage 91 in the rotating coilerplate, falling as it issues from the said sliverpassage into the usual can (not shown) placed in position to receive the same.

The shaft 71 of the coiler-roll 7 is fitted to a bearing in a stand '72, (shown separately in Figs. 8 and 9,) the said stand being fixed by bolts 73 and nuts-74 toa suitable portion 11, shown integral with the side casing 1. The bolts 73 pass through slots 75 75, which are provided in the foot portion or flange of stand 72 for the purpose of enabling the stand to be adjusted lengthwise of the shaft and roll as may be required in setting the parts in proper relations to one another. The shaft 71 has fixed thereon at the end thereof opposite I to that which carries the roll 7 aspur-pinion 76 and bevel-gear 77, the latter meshing with a like bevel-gear 10, fast upon the upper end of the upright coiler-shaft 101. The said upright shaft 101 has rotary motion communicated thereto in suitable manner and through the bevel-gears 10 and 77 drives the roll 7.

' roll 8.

Adjacent its upper end the said upright shaft is supported by a bearing 104.

The shaft of the coiler-roll 8 is fitted to a bearing in a stand 82 (shown separately in Figs. 5, 6, and 7) and is furnished with a spur-pinion 84, meshing with the spur-pinion 76. Through the spur-pinions 76 and 84 the coiler-roll 8 is rotated in unison with coilerroll 7. Stand 82 is furnished with a vertical bearing 87 at the end thereof opposite to that at which the roll 8 is located, this bearing fitting an upright stud 89, that is secured to a suitable part of the fixed upper part of the coiler-frame. The said stand 82 is free to turn around this upright stud 89 as upon a pivot, so as to enable its roll 8 to approach the roll or recede from the latter. For the purpose of keeping the roll 8 pressed toward the roll 7 with a yielding force the spring 17 is provided,the latter beingheld fastat oneend by one of the securing-bolts 73 and its nut 74, while its free extremity is upturned to form apivot 171, on which lastis mounted the handlever 172, havingthe eccentric hub 173 formed with two fiat sides or faces, one thereof farther from the axis of the said pivot than the other. The position of the saidhand-lever, which is represented in Fig. 4, causes the side or face which is the more remote from the axis to bear against the side of stand 82,

thus placing spring 17 under tension, which operates to press stand 82 and roll 8 toward roll 7. When hand-lever 172 is swung so as to place its other face or side next the stand 82, the pressure against stand 82 is relaxed and the roll 8 is permitted to move slightly away from roll 7. For the purpose of enabling the bearings for the shafts of the two rolls conveniently to be supplied with lubricant one of thestands containing such bearings, herein the fixed stand 72, (see Figs. 8 and 9,) is furnished with an oil-cup 78, from the bottom of which an oil-hole 79 leads into the bearing for shaft 71. The other of the said stands, herein the movable stand 82, Figs.'5, 6, and 7, is furnished with an oilcup 85, from the bottom of which an oil-hole 86 leads into the bearing for the shaft of The oil-cup 85 is elongated and projects over the top of the fixed stand 72, (see Fig. 10,) it being furnished with asecond oilhole 80, discharging into the oil-cup 78 in said fixed'stand 72, the oil-cup having sufficient area to catch oil flowing through oil-hole in the various positions of the movable stand 82. For the purpose of enabling the bearing 104'for the upright shaft 101 to be supplied with lubricant the bore or eye of the bevelgear 10, fast upon the upper end thereof, is formed with a longitudinal groove, as 107. This forms an oil-passage that permits oil that is poured upon the top of said bevel-gear to flow down through the said groove 107 and along the shaft 101 to the bearing 104, the top of which is slightly cupped, as shown in Figs. 65

'purpose of placing oil in the oil-cups and 12 through an opening 145 in the movable cover portion 2, the said opening being pro vided with a door 14, which is hinged on a vertical pivot 141 at one corner, so as to swing in a horizontal plane about said pivot, it being furnished with a knob or handle 143 for convenience in moving the same and its opposite ends being arranged to fit closely into rabbets 144 and 147, which are formed for the reception of such ends in the raised sliverguide 4 and trumpet 5.

What I claim is 1. In a coiler, in combination, the trumpet; the rolls receiving sliver from the said trumpet; and the stands provided with bearings for the respective rolls, movable relatively to each other to enable the rolls to approach or recede from each other, and each provided with an oil-cup and an oil-hole leading from said oil-cup to the corresponding bearing, one

vof said oilcups overhanging the other and having an oil-hole through which lubricant may pass into the lower oil-cup, substantially as described.

2. In a coiler, in combination, the coiler frame or support; the cover portion having an opening provided with a movable door to close said opening; the trumpet; the rolls beneath ,said cover portion receiving sliver from the said trumpet; and the stands carried by the coiler frame or support, provided with bearings for the respective rolls, movable relatively to each other to enable the rolls to approach or recede from each other, and each provided with an oil-cup and an oil-hole leading from said oil cup to the corresponding bearing, one of said oil-cups overhanging the other and having an oil-hole through which lubricant may pass into the lower oil-cup, the movement of the said door affording access to the said oil cups; substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
